Build an Amazon Prime or Costco type of membership. Charge a recurring fee and in exchange, give members exclusive rewards and perks. This can include giving discounts, free shipping & exclusive access to content and products. Also reward members with store credit, where it can be used as a form of payment on the checkout page. Store credit can be given as a sign-up bonus, redeemed from reward points earned from purchases, recurring credits or even convert membership fees to store credit.
